Drop the song you downloaded from Suno. This page measures where its sound stops and whether it clips, then says whether the trouble is in the file or in the song.

Measured in your browser. Your file is not uploaded.
The MP3 or WAV you downloaded yourself, up to five minutes. FLAC, M4A, OGG and Opus usually work too.
Time runs left to right and pitch rises upward, to 24 kHz at the top; brighter is louder. When the top is missing, the empty band above the cutoff is outlined. An encoder's cut usually shows as a straight edge across the whole song.
Solipsium's free try is built for speech. For music, a free account's editor can run AudioSR on a passage of up to 60 seconds, and what it adds is inferred.
Make a free accountCounted the way the editor's scan counts: two or more samples in a row at full scale, or three or more loud samples at exactly the same level. A loud MP3 can pass full scale when it is decoded, and that counts too; when the song's peaks pass full scale, the line above says so.
What the answer means
A song can sound dull because the file lost its top when it was made, or because the song itself is crowded or dark. The picture tells them apart, and each points to a different next step.
Above the cutoff the file holds almost nothing, and an equaliser cannot add back treble that is not there. If your plan offers a WAV download, check that file too. A free account's editor can run AudioSR on up to 60 seconds of a song, and what it adds is inferred.
Make a free accountThen the dullness is in the song: instruments crowding the voice, or a dark arrangement. Regenerate or rebalance the section. If your plan gives you stems, turn down what crowds the voice before you master.
Clipping flattens the loudest peaks, which can sound harsh. Turning the file down afterwards does not undo it; a master with more headroom avoids it.
Questions
Either the file lost its top when it was made, which this page measures, or the song itself is crowded or dark, which a regeneration or a remix of its stems changes. A song can have both.
Suno does not publish the bitrate or the frequency range of its downloads, so this page does not assume one: it measures your file. Suno's help centre, read on October 15, 2026, says MP3 downloads are available on every plan and WAV only to Pro and Premier subscribers, and that the free plan's Download button makes a lightweight MP3. Solipsium is not connected with Suno.
No. Suno's terms (last revised August 10, 2026) forbid getting a copy of a song in any way other than its own downloads, for example by recording or stream ripping, so this page checks only a file you downloaded yourself.
Mastering changes balance and level. It can brighten the treble a file still holds, but it cannot add back treble the file no longer holds.
Suno's terms, last revised August 10, 2026, let you edit, process or convert a song you are allowed to use “to the extent such use is incidental”, and forbid removing or altering the watermark or metadata Suno adds to an Output if the aim is to hide where the song came from. Whether a given repair counts as incidental is between you and Suno. This page only reads your file and changes nothing in it.
Yes, for MP3, WAV and FLAC files up to five minutes long, and for M4A, OGG and Opus files your browser opens: an M4A saved in Apple's ALAC format opens only in Safari, and an older Safari may not open OGG or Opus. Udio turned off downloads on October 29, 2025, so most Udio songs that can be checked were saved before then.
With a free account, open the song in the editor and run AudioSR on the passage you choose.
